Active Data
Active data is information residing on the direct access storage media of computer systems, which is readily visible to the operating system and/or application software with which it was created and immediately accessible to users without undeletion, modification or reconstruction (i.e., word processing and spreadsheet files, programs and files used by the computer’s operating system).
Active Records
Active records are records related to current, ongoing or in process activities and are referred to on a regular basis to respond to day-to-day operational requirements. An active record resides in native application format and is accessible for purposes of business processing with no restrictions on alteration beyond normal business rules.
Application
An application is a collection of one or more related software programs that enables a user to enter, store, view, modify or extract information from files or databases. The term is commonly used in place of "program" or "software." Applications may include word processors, Internet browsing tools and spreadsheets.
Archival Data
Archival data is information that is not directly accessible to the user of a computer system but that the organization maintains for long-term storage and record keeping purposes. Archival data may be written to removable media such as a CD, magneto-optical media, tape or other electronic storage device, or may be maintained on system hard drives in compressed formats (i.e., data stored on backup tapes or disks, usually for disaster recovery purposes).
Archive/Electronic Archive
Archives are long term repositories for the storage of records. Electronic archives preserve the content, prevent or track alterations and control access to electronic records.
Attachment
An attachment is a record or file associated with another record for the purpose of storage or transfer. There may be multiple attachments associated with a single "parent" or "master" record. The attachments and associated record may be managed and processed as a single unit. In common use, this term refers to a file (or files) associated with an e-mail for transfer and storage as a single message unit. Because in certain circumstances the context of the attachment—for example, the parent e-mail and its associated metadata—can be important, an organisation should consider whether its policy should authorize or restrict the disassociation of attachments from their parent records.
Attribute
An attribute is a characteristic of data that sets it apart from other data, such as location, length, or type. The term attribute is sometimes used synonymously with "data element" or "property."
ASCII
(Acronym for American Standard Code) ASCII is a code that assigns a number to each key on the keyboard. ASCII text does not include special formatting features and therefore can be exchanged and read by most computer systems.
Author /Originator
The author of a document is the person, office or designated position responsible for its creation or issuance. In some cases, the software application producing the document may capture the author's identity and associate it with the document.
Backup
To create a copy of data as a precaution against the loss or damage of the original data. Most users backup some of their files, and many computer networks utilize automatic backup software to make regular copies of some or all of the data on the network. Some backup systems use digital audio tape (DAT) as a storage medium.
Backup Data
Backup data is information that is not presently in use by an organisation and is routinely stored separately upon portable media, to free up space and permit data recovery in the event of disaster.
Backup Tape
Backup tapes are portable media used to store data that is not presently in use by an organisation to free up space but still allow for disaster recovery.
Backup Tape Recycling
Backup tape recycling is the process whereby an organisation’s backup tapes are overwritten with new backup data, usually on a fixed schedule (i.e., the use of nightly backup tapes for each day of the week with the daily backup tape for a particular day being overwritten on the same day the following week; weekly and monthly backups being stored offsite for a specified period of time before being placed back in the rotation).
Bandwidth
The amount of information or data that can be sent over a network connection in a given period of time. Bandwidth is usually stated in bits per second (bps), kilobits per second (kbps), or megabits per second (mps).
Bates Production Number
A bates production number is a tracking number assigned to each page of each document in the production set.
Binary
Mathematical base two, or numbers composed of a series of zeros and ones. Since zeros and ones can be easily represented by two voltage levels on an electronic device, the binary number system is widely used in digital computing.
Bit

Compression
A technology that reduces the size of a file. Compression programs are valuable to network users because they help save both time and bandwidth.
Computer Forensics
Computer forensics is the use of specialized techniques for recovery, authentication, and analysis of electronic data when a case involves issues relating to reconstruction of computer usage, examination of residual data, authentication of data by technical analysis or explanation of technical features of data and computer usage. Computer forensics requires specialized expertise that goes beyond normal data collection and preservation techniques available to end-users or system support personnel.

De-duplication
De-duplication ("De-duping") is the process of comparing electronic records based on their characteristics and removing duplicate records from the data set. This process can be done one of two ways. First, in universal or case (level) de-duplication, only a single copy of each document is retained across a whole case. Second, in custodian de-duplication, a single copy of each document is retained within any single custodian. In custodian (level) de-duplication, there will be duplicates across the whole case, but also visibility into which custodians had possession of a copy of a particular document. De-duplication may be done by comparing documents' hash values, which identifies exact copies, or by technology that identifies duplicates with only minor, non-substantive differences.
Deleted Data
Deleted data is data that, in the past, existed on the computer as live data and which has been deleted by the computer system or end-user activity. Deleted data remains on storage media in whole or in part until it is overwritten by ongoing usage or "wiped" with a software program specifically designed to remove deleted data. Even after the data itself has been wiped, directory entries, pointers, or other metadata relating to the deleted data may remain on the computer.

Electronic Record
Information recorded in a form that requires a computer or other machine to process it and that otherwise satisfies the definition of a record.
Email Message Store
A top most e-mail message store is the location in which an e-mail system stores its data. For instance, an Outlook PST (personal storage folder) is a type of top most file that is created when a user’s Microsoft Outlook mail account is set up. Additional Outlook PST files for that user can be created for backing up and archiving Outlook folders, messages, forms and files. Similar to a filing cabinet, which is not considered part of the paper documents contained in it, a top most store generally is not considered part of a family.

Format
The internal structure of a file, which defines the way it is stored and used. Specific applications may define unique formats for their data (e.g., “MS Word document file format”). Many files may only be viewed or printed using their originating application or an application designed to work with compatible formats. Computer storage systems commonly identify files by a naming convention that denotes the format (and therefore the probable originating application) (e.g., “DOC” for Microsoft Word document files; “XLS” for Microsoft Excel spreadsheet files; “TXT” for text files; and “HTML” (for Hypertext Markup Language (HTML) files such as Web pages). Users may choose alternate naming conventions, but this may affect how the files are treated by applications.

The specific communication to business or IT organisations may also be called a “hold,” “preservation order,” “suspension order,” “freeze notice,” “hold order” or “hold notice.”
Logical Failure
In these situations the physical state of the hard drive is in working condition, however, something has gone wrong with the logical storage system on the drive itself. Logical failures can be due to many reasons, here are some of the most common:
- Virus (see virus)
- Formatted drive or disk partition: By formatting a drive or creating a new disk partition we reset the hard drive back into a factory-like setting with a brand new file system, ready for a new operating system to be installed
- File deletion: When files are deleted they are not erased – the area of the drive that stores those specific files is marked available to be overwritten with new data, whereas erasing files actually resets the area of the drive where the files were stored back to a factory reset-like state
Megabyte (MB)
A megabyte is a measure of computer data storage capacity and is roughly a million (1,000,000) bytes (1,048,576 actual bytes).
Metadata
Metadata is information about a particular data set which may describe, for example, how, when and by whom it was received, created, accessed and/or modified and how it is formatted. Some metadata, such as file dates and sizes, can easily be seen by users; other metadata can be hidden or embedded and unavailable to computer users who are not technically adept. Metadata is generally not reproduced in full form when a document is printed. (Typically referred to by the less informative shorthand phrase “data about data,” it describes the content, quality, condition, history and other characteristics of the data.) There is a file system metadata, document metadata and e-mail metadata. Furthermore, e-discovery vendors often create and maintain vendor-added metadata as a result of processing a document.
Migrated Data
Migrated Data is information that has been moved from one database or format to another, usually as a result of a change from one hardware or software technology to another.

The terms “load” and “loading” are often used in conjunction with, or synonymously with, “mount” and “mounting” (as in “mount and load a tape”). “Load” may also refer to the process of transferring data from mounted media to another media or to an on-line system.
Native Format
The source document, as collected from a source computer or server, before any conversion or processing. Electronic documents have an associated file structure defined by the original creating application. This file structure is referred to as the “native format” of the document. Because viewing or searching documents in the native format may require the original application (for example, viewing a Microsoft Word document may require the Microsoft Word application), documents are often converted to a standard file format (i.e., tiff or PDF) as part of electronic document processing.

Physical Failure
A failure to the internal components or electronics of a hard drive. The causes can include: knocks/drops, water, power failure etc. This type of failure encompasses three main sub categories:
- Physical media damage: Physical damage to the platters where the data is stored. This can be in the form of scratches or dents on the platter. This failure is caused when the reading head comes into contact with the surface of the platters either when it is stopped or when it is in operation
- Electronic failure: This occurs when there is an anomaly in the power supply or an overload of the electrical circuit causing a power surge that burns the electronics attached to the circuit board
- Mechanical failure: These are failures to the internal parts of the hard drive. There are many causes for a mechanical failure, but the most common is overheating of the hard drive which causes the platter to dilate, consequently the read/write head can be wrongly positioned
Plain Text
The least formatted and therefore most portable form of text for computerized documents.
Pointer
A pointer is an index entry in the directory of a disk (or other storage medium) that identifies the space on the disc in which an electronic document or piece of electronic data resides, thereby preventing that space from being overwritten by other data. In most cases, when an electronic document is “deleted,” the pointer is deleted, which allows the document to be overwritten, but the document is not actually erased.

Residual Data
Residual data (sometimes referred to as “ambient data”) refers to data that is not active on a computer system. Residual data includes (1) data found on media free space; (2) data found in file slack space; and (3) data within files that has functionally been deleted, in that it is not visible using the application with which the file was created, without use of undelete or special data recovery techniques.
Restore
To transfer data from a backup medium (such as tapes) to an on-line system, often for the purpose of recovery from a problem, failure or disaster. Restoration of archival media is the transfer of data from an archival store to an on-line system for the purposes of processing (such as query, analysis, extraction or disposition of that data). Archival restoration of systems may require not only data restoration but also replication of the original hardware and software operating environment. Restoration of systems is often called “recovery”.
Router
